76 years old and very pleased with knee replacements
What I would expect from a good warranty:
I expect the warranty to indicate that the work was done properly, the device was well made and will not deteriorate with normal use, and that the company that made the device will contact me or my surgeon (who will then contact me) if there are unexpected situations that arise connected to the exact implant that I received.
I had one knee replacement in 2005 and the other knee replaced in 2010, and the same surgeon did both operations. I told the doctor (who does over 300 knee surgeries a year) that I wanted his choice of what would be the appropriate knee for my age and activities. I was extremely well pleased with both surgeries. I’m 76 years old; I walk without a cane, and I can alternate feet going up and down stairs.
